I'm looking for new vent covers, these are old and look pretty crappy. The problem is that like most things in this house, they are not a standard size.

They measure 24x8 external and 21.5x6 internal with a screen attached to keep crap from falling into the vent.

Does anyone know where I can find something like this or is there anyone on here that could custom make some nice looking ones, I need 3 of them? I understand they won't be cheap.

Here's what we have.
